8x+9y=11
9y=-6x+11
y=-6x/9+11/9
y=-2x/3+11/9
Graphing this equation we get:
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+-2x%2F3+%2B11%2F9%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, -2x/3 +11/9).
(-6,8)
8*-6+9*8=11
-48+72=11
24=11
Thus (-6,8) are not valid answers to the x & y values in this equation.
Also the x & y values in the table don't fit this equation.
